A segregated fanzone has been erected for Northern Ireland football supporters travelling to Poland this weekend amid fears of violence at a World Cup qualifying match between the two countries.
Polish authorities have built the dedicated area in the city of Katowice - where the match will be played on Saturday night - in a bid to ensure the event passes off without incident.
The move comes after serious rioting broke out between rival supporters at the corresponding fixture in Belfast in March.
As well as the cordoned off zone in Katowice city centre, the Irish Football Association has organised coaches to the stadium for those who have decided to avoid Katowice and stay elsewhere in Berlin and Krakow.
Fans' group the Amalgamation of Official Northern Ireland Supporters Clubs (AONISC) has also set up a special mobile phone network service to inform its members of places to avoid during their trip.
IFA officials recently travelled to Poland with PSNI officers and representatives from the AONISC to seek safety assurances from the host nation.
Raymond Kennedy, President of the IFA said he hoped the measures would result in a trouble free occasion.
"These activities have been organised with the fans' safety of paramount importance and should ensure the safety of the Northern Ireland supporters," he said.
"We would urge all supporters to be aware of the fan zone and not to meet anywhere outside of the dedicated area.
"I think it is important to let the fans know that plans are in place and if they are followed will provide some form of comfort for our travelling support."
Gary McAllister, from the AONISC said: "The Irish FA and PSNI have worked tirelessly on behalf of Northern Ireland's fans in the months running up to Saturday's game, and the Amalgamation and its members are extremely grateful for their efforts."
He said fans could register for the text service by emailing
